The short answer: Commercial heating systems compared — boilers, heat pumps, district heating, and radiant systems. Which is right for your industrial or commercial building
Heating a commercial building is essential to creating a comfortable environment for all who work within it. Different types of commercial heating systems exist, and each has its own benefits and drawbacks.
It is important to understand the differences in order to make the best choice for your building and your budget.
Gas-fired boilers are the most common heating system in UK commercial buildings. They use natural gas to heat water, which is then distributed via radiators or underfloor heating. Modern condensing boilers achieve efficiencies above 90%.
Air source heat pumps extract heat from outside air and transfer it into the building. They are electrically powered and can achieve coefficients of performance (COP) of 3 or above — meaning 3kW of heat output per 1kW of electricity input. ASHPs are increasingly used in new commercial builds as part of decarbonisation strategies.
Ground source heat pumps extract heat from the ground via buried loops. They are more efficient than ASHPs in cold weather but require more installation space and upfront cost.
District heating distributes heat from a central source to multiple buildings via insulated pipes. It is common in large commercial and mixed-use developments.
Radiant heating systems emit infrared radiation directly to heat occupants and surfaces rather than warming air. They are particularly effective in large industrial spaces, warehouses, and workshops where heating the air volume is impractical.

The main commercial heating systems are gas-fired boilers (the most common in the UK), air source heat pumps, ground source heat pumps, district heating, and radiant heating systems. Each has different efficiency profiles, installation requirements, and running costs. The best choice depends on building size, occupancy pattern, fuel availability, and decarbonisation targets.
Heat pumps offer the highest theoretical efficiency, with coefficients of performance (COP) of 3–4 under typical UK conditions, meaning 3–4 units of heat output per unit of electricity consumed. Modern condensing gas boilers achieve 90–94% efficiency. The most cost-effective system depends on local gas and electricity prices and the specific building’s heat demand profile.
For large industrial spaces with high ceiling heights and intermittent occupancy — such as warehouses, workshops, and factories — radiant heating is often the most practical solution because it heats surfaces and occupants directly rather than the air volume. For office buildings and continuous-use commercial premises, modern condensing boiler systems or heat pumps are typically the most appropriate.
Commercial gas boilers should be serviced annually by a Gas Safe registered engineer. Heat pumps typically require annual checks. For buildings covered by the Gas Safety (Installation and Use) Regulations 1998, annual gas safety checks are a legal requirement. Regular servicing extends system life, maintains efficiency, and satisfies insurance and compliance requirements.
